摘　　要：转炉冶炼过程控制、终点控制是影响炼钢生产效率、产品质量、生产成本等指标的关键,但大部分钢铁企业的转炉冶炼控制主要依赖于人工经验。中天钢铁集团有限公司联合湖南镭目科技有限公司率先研究开发了基于声呐化渣、火焰分析和烟气分析的非副枪转炉智能化炼钢系统,实现了在无副枪情况下的全程无人工干预“一键式”炼钢。该系统对冶炼过程的自动化控制取得了良好效果,一倒碳质量分数(≤0.15%)预报在误差±0.02%内命中率达到90%,一倒温度预报在误差±15℃内命中率达到87%,一倒磷质量分数预报在误差±0.005%内命中率达到90%,喷溅识别准确率达到99%,为钢铁企业发展智能化炼钢起到积极的推进作用。Converter smelting process control and end-point control are key to affecting steelmaking production efficiency,product quality,production cost and other indicators.However,converter smelting control of most steel companies mainly relies on manual experience.Zhongtian Iron and Steel Group Co.,Ltd.and Hunan RAMON Technology Co.,Ltd.took the lead in researching and developing the non-sublance converter intelligent steelmaking system based on sonar slagging,flame analysis and flue gas analysis,realizing the whole process of“one-click”steelmaking without manual intervention under the circumstance of non-sublance.The system has achieved good results in the automation control of the smelting process.At the first turning down,the hit rate of carbon mass fraction(≤0.15%)prediction within the error range of±0.02%was 90%,the hit rate of temperature prediction within the error range of±15℃was 87%,and the hit rate of phosphorus mass fraction prediction within the error range of±0.005%was 90%.In addition,the accuracy rate of splash recognition reached 99%.These achievements play a positive role in promoting the intelligent steelmaking development of iron and steel enterprises.
